There were some changes in move-generator and minor change in evaluation function. Classic Alpha-Beta search with hash table and time management remains unchanged. This version is used in the standard group for Gomocup 2018.

An open-source Gomoku program. The AI algorithm was one of the strongest as for 2002 and it’s reasonable even now. It is ported to Gomocup interface and further improved by Petr Lastovicka. Carbon supports freestyle, standard, and renju rules.

AI is based on alpha-beta pruning of minimax agorithm with simple hash-table. Search depth at fast game is 2 half-move. Board size is supported from 15x15 to 20x20. Rule of win is selectable - exactly five wins or five and more wins. Program is written in C.

The program has three main components: an opening book for the early game, a Monte-Carlo tree search algorithm, a heuristic evaluation function tuned by the cross-entropy optimization algorithm. It was not used in the tournament since 2016 because its memory usage exceeds the quota too often on Windows 10.

AI Trunkat, the winner of Gomocup 2002. You can set up it's difficulty by renaming from trunkat1.exe to trunkat5.exe. A file CSWDPMI.EXE is required to be in the same directory with the brain. The program si written in DOS and it is not xompatible with Windows 8 and higher.
